簡約 3+1/3-1/12-(1-(2 1/4+1.7))

解

簡約

3 + \frac{1}{3} - \frac{1}{12} - (1 - (2 \frac{1}{4} + 1.7))

6 \frac{1}{5}

十進法表記

6.2

解答ステップ

3 + \frac{1}{3} - \frac{1}{12} - (1 - (2 \frac{1}{4} + 1.7))

帯分数を仮分数に変換する:

2 \frac{1}{4} = \frac{9}{4}

= 3 + \frac{1}{3} - \frac{1}{12} - (1 - (\frac{9}{4} + 1.7))

- (1 - (\frac{9}{4} + 1.7)) = \frac{59}{20}

= 3 + \frac{1}{3} - \frac{1}{12} + \frac{59}{20}

3 + \frac{1}{3} - \frac{1}{12} + \frac{59}{20} = \frac{31}{5}

= \frac{31}{5}

仮分数を帯分数に変換する:

\frac{31}{5} = 6 \frac{1}{5}

= 6 \frac{1}{5}
